    JeiFuRi writes "Around 50,000 years ago, many large Australian animals died off with the arrival of man. From a study carried out by the Carnegie Institution, we now know that the continent's earliest settlers caused these extinctions through their use of fire. In addition, it may have altered the ecosystem of ancient Australia and brought about it's collapse. Futher commentary at BBC News, newKerala, and Red Nova." "Know" is a strong word; the study suggests this may be the case, though.

    purduephotog writes "CDAC has announced the formation of a new form of hexagonal packed carbon similiar to diamond. Carbon nanotubes are compressed at 75 GPa and quenched. The new material is conclusively different via Raman Spectroscopy and both cracked and indented the diamond anvil used in its creation. CDAC is also known to have created via CVD the hardest diamond to date."
